"In a statement given to Reuters, Apple said that Wyden's letter gave them the opening they needed to share more details with the public about how governments monitored push notifications."
Just as an aside on metadata, I find it really frustrating that I can't just read the statement. There's a MacRumors article about a Reuters article about something Apple told them. I went to the Reuters article, but it still only contains one quote pulled from "a statement". I don't imagine Apple sent a major news organization an on-the-record statement with the restriction that they were only allowed to paraphrase it.
